USB 3.0 header to dual USB A adapter Function: Converts the USB 3.0 19/20 pin header on the motherboard to two USB 3.0 Type A female ports. It provides dual USB 3.0 ports from a single 19/20 pin header. Compatibility: Works with standard USB 3.0 19/20 pin motherboard headers. Suitable for most PC builds where internal USB 3.0 expansion is needed. Performance: USB 3.0 interface supports speed data transfer for compatible devices. Delivers up to USB 3.0 performance on two Type A ports. Design and construction: Compact internal adapter designed for use inside a PC case. Provides durable connections between the motherboard header and the two USB A ports. Size and form factor: Small form factor that fits typical internal PC layouts and front panel mounting scenarios without bulk. Use scenarios: 1) Add two USB 3.0 ports to a PC case front panel by wiring from the motherboard 19/20 pin header. 2) Provide convenient internal USB 3.0 access for speed devices such as external USB drives, docking peripherals, or data rate peripherals during system builds. 3) Use in workstation or gaming builds where extra USB 3.0 ports are required without expanding external front panels. Key benefits: Simple internal expansion of USB 3.0 connectivity from one header to two ports. Maintains USB 3.0 performance for rapid data transfer. Easy integration with standard motherboard headers for reliable operation.
